在 macOS 问题上安装 py3exiv2

Question

我想校准相机镜头，为此，我按照此处的说明进行操作。 根据说明，我需要来自此处的 python3-exiv2 依赖项。

当我尝试运行它时：

pip3 install py3exiv2

我明白了：

我不知道从哪里开始这个输出。 谁能建议我此时可以尝试什么？

运行以下内容没有帮助：

brew boost-python

Answer 1

您面临的问题是因为在 MacOS 新版本上，pip3 没有在正确的位置查找头文件。 在这里查看我的答案： https ://answers.launchpad.net/py3exiv2/+question/700064

这就是为我解决的问题：

要解决此问题，请执行以下操作：

brew install boost-python3 gexiv2 pygobject3

安装依赖项后，您将面临更多错误。 要解决这些问题，请设置正确的包含和链接器路径，然后使用 pip 安装模块。

export CPLUS_INCLUDE_PATH=/usr/local/Cellar/exiv2/0.27.5_1/include/:/usr/local/opt/libssh/include/:/usr/local/Cellar/boost/1.76.0/include/
export LDFLAGS="-L/usr/local/Cellar/boost-python3/1.76.0/lib -L/usr/local/Cellar/exiv2/0.27.5_1/lib"

 pip install py3exiv2

或者如果您使用的是 pipenv

 CPLUS_INCLUDE_PATH=/usr/local/Cellar/exiv2/0.27.5_1/include/:/usr/local/opt/libssh/include/:/usr/local/Cellar/boost/1.76.0/include/ LDFLAGS="-L/usr/local/Cellar/boost-python3/1.76.0/lib -L/usr/local/Cellar/exiv2/0.27.5_1/lib" pipenv install
